Paremd Mar. 1s, 1930 EDWIN D. CODDINGTON, OF NORTH MILWAUKEE, WISCONSIN REENFORCED BUILDING FABRIC Application led August 6, 1923. Serial ',No. 655,917.

This invention relates to improvements in reenforced building fabric of the class and for the same general purposes as that shown and described in United States Letters Patent 5 No. 1,164,334, issued to me December 14, 1915, and in my pending application Serial No.

537 ,717, filed February 20, 1922.

The main objects of the invention are to further stiften such fabric; tovfacilitate the application of plaster thereto; to admit of the use of thinner coatings of plaster and hence effect a saving of plaster; to provide for a more effective bonding of the plaster to the fabric; and generally to improve the construction of fabric of this class.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like characters designate the same parts in the several figures.

Figure 1 is a face view of a piece of reenforced fabric'embodying the invention; Fig. 2 is a section on the line 2-2, Fig. 1; Fig.

3 is an enlarged cross section of one of the auxiliary metal reenforcing strips; Fig. 4 is a face view similar to Figpl of a piece of reenforced fabric embodying the invention in a modified construction; and Fig. 5 is a section on the line 5.-5, Fig. 4.

J Referring to Figs. 1, 2u and 3, the fabric comprises a flexible sheet a, of suitable fibrous material such as the wellknown building felt of commerce, which is ordinarily and preferably saturated or coated with tar, asphalt or' the like, to make it impervious to moisture.

The sheets are reenforced at suitable in- 40 tervals with hard drawn, resilient, or annealed or partially annealed and more or less flexible metal wires b, which are woven-1n and out through the sheet. The reenforcing wires may run crosswise of the sheet parallel with one another sides of the sheet, but may be variously arranged and placed as illustrated in saidrLetters Patent, according to thenature and purpose of the structure to iwhich the fabric is to be applied.

and with opposite ends or Between one side of the sheet a and the wires b, -auxiliary metal| reenforcing and stifening strips c are inserted transversely to the wires which impart an undulatory form to the sheet. t

It has been found that in applying plaster to the reenforcing fabric the trowel presses the portions of sheet a between members c inwardly. When the trowel passes over the ortions of sheet a between reenforcing memers c, these portions spring outwardly again to assume their former position,4 and in so doing dislodge the plaster which has just been applied by the trowel. To prevent this bulging or springing action of the portions of sheet a between reenforcing members c, and to increase the stiffness and stability of the sheet between members c, the reenforcing wires b are woven through sheet a at a plurality of points, or at closer intervals or in shorter stitches intermediate reenforcing members c, as shown in Fig. 1, to provide a stitch or a number of stitchesy between these members.

It has been found from experience that this weaving of wires b through the portions of sheet a between reenforcing members c makes it possible to readily apply plaster to the fabric so that -a fewer number of coats ofbplaster are needed to make a satisfactory Satisfactory results have been obtained by weaving wires b through sheet a, as shown in Fig. l, to make a double stitch through the portions of sheet a between reenforcing mem- 85 bers c. t

The strips or members c are corrugated lengthwise to stifen them, being formed with a ctdntral rib d, which is placed next to the sheet, and with marginal wings or flanges e, g

overhanging the sheet at a distance therefrom, to receive plaster between them and the sheet and formclenches or bon'ds there` with.

At the junction of the flanges e with the sides of the ribs d are formed small outward- 1y projecting beads or ridges f, to which the 'overlying reenforcing wires b are secured'at suitable intervals, as shown at g in Figs. 1 and 2, by electric welding or soldering, the

contact between the wires and strips o and facilitating the welding or solderino` of the arts together and preventing breaking own, weakening or injury of the thin metal 'strips by excessive heating. Thus rigidly .fastening the wires b to the strips c at inter- Isections thereof, prevents them from slipping upon one another, and materially stifens the fabric,I enabling it` to resist the pressure of tools used in the application of plaster thereto without flexure or displacement of the fabric, facilitating the application of the plaster and admitting of the use of athinner coating of plaster.

Referring to Figs. 4 and 5, showing a modification of the fabric, the auxiliary reenforcing andstilfeningstrips 0 are made of wood, and are fastened at intervals to the overlying reenforcing wires b so as to prevent their slipping or displacement relative thereto, as by staples g.

Thef fabric constructed in either of the waysshown and described, is made in sheets or sections of any convenient or desired dimensions, which can be piled or stacked flat, ne upon another, and bundled in small com- Vpass for storage andtransportion and in the most convenient condition for immediate application to a building.

In laying the sheets, they are-lapped at the edges and fastened to the studding or frame members h of the structure to which they are applied, in any suitable manner, as set forth in said Letters Patent, or otherwise.

In either construction, the strips cj or c being fastened at intervals to the wires b, are held to the wires so that the plaster when alpplied to the fabric, will push the flexible s eets slightly away .from the backs of the strips, and will pass between them and the sheets and thus completely surround and imbed the strips in the plaster, avoid air pockets, and form themost effective clenches or bonds between the plaster and fabric, besides protecting the strips from the air and preventing thelr corrosion or disintegration.

The reenforcing members of the fabric fastened together at intersections, so that they Will not shift their positions relative to one another, anchor the plaster in which they are imbedded and prevent it while in a plastic condition, from sliding out/of place or shiftin on the fabric. L he plaster filling .the deeper depressions 1n the sheets adjacent the auxiliary stiifening strips c or c', forms on the back of the plaster coating next to the sheets, corrugations or ribs which also materially stiifen andu strengthen the finished structure without correspondlngly increasing the quantity of plaster required to properly coat the fabric.

The auxiliary ribbed metal reenforcing stri s c facilitate fastening the fabricto the stu ding or framework of a structure by nailing according to customary ractice of lathers, the nails, indicated at j, ig. 2, be-

ing centered and guided in driving by the grooves formed in the outer faces 'of the strips by the ribs d.

Various modifications in detailsof construction and arrangement of arts of the fabric, other than those speci ed, may be rmade-.without departure from the princi le and scope of the invention as defined in t e following claims. For example, the shape and arrangement of the metal auxiliary reenforcing and stifl'ening strips c may be varied Land in some cases they, orsome of them, may4 be placed outside of the wires b and welded,

soldered or otherwise rigidly fastened 'therel ing a flexible sheet of fibrous material, metal reenforcing wires woven at intervals through the sheet and forming undulations therein transversely to the wires, and auxiliary metal reenforcing and stilfening strips inserted between the sheet and wires and each formed with a longitudinal rib next to the fabric and marginal wings overhangin the sheet and adapted ,to form clenches -wit a plaster coating.
